【摘要】 通过对7名优秀青年男子跳高运动员助跑最后阶段及起跳技术的三维生物力学分析,提出我国优秀青少年男子跳高运动员倒数第2步缓冲动作过大,摆动腿蹬离地面时速度水平较低;起跳脚着地时的身体质心水平速度水平较高;起跳结束瞬间的垂直速度水平差别较大;起跳蹬伸距离的长短与起跳垂直速度水平并无直接的相关;起跳垂直速度水平与起跳时间有较高的相关等结论。更多还原

【Abstract】 With the three-dimensional biomechanics analysis of Chinese seven elite young male high jumpers’ jump-up technology in the last stage of the run-up process,the conclusions are drawn that the extent of support leg’s buffer stage are too long and the extending velocity of swing leg are too small in the second step at the end of run-up process;that the horizontal velocity of body’s center of gravity when the take-off leg access the ground are relatively high;that there are some large differences in the vertical velocity of the jump-up stage’s finish point which are not directly connected with the extent of jump-up leg’s extension and are related with the jump-up time.更多还原
